How do you like the GM-X ground effects? Did it require and sanding or prep before paint?
And im guessing it installs like the GM one. Sorry for all the questions lol

Thanks man, I love it! Completely changed the look of the car. I bought it already painted from GMPartshouse so yes it installs just like the GM kit bc it is. Very high quality and the fit and finish is excellent

Oh and the only prep was cleaning the areas on the bumpers with alcohol to make sure the 3M tape adheres properly.
